摘　　要：目的确保生活饮用水总α和总β放射性测量结果的准确度,提升实验室检验能力,减少各种因素造成的结果误差。方法依据国家标准对水样进行总放射性水平分析。结果 2014年总α和总β放射性测量值的标准偏差均<10%,其中总α放射性测量值的标准偏差为9.30%,高于总β放射性测量值的标准偏差3.28%,比对考核结果优秀。2009年、2010年、2014年、2016年比对测量结果中总β放射性测量值的标准偏差均<15%,2009年、2010年总α放射性测量值的标准偏差均>20%。结论水样总放射性检测过程中,应重视每一个环节的质量控制,确保检测结果的准确性。通过实验室比对,发现实验室水样总放射性测量过程中存在的问题,提升实验室人员检验能力。Objective To ensure the accuracy of radioactivity results in the measurement of total α and total β in drinking water, to improve the laboratory testing ability, and to reduce the errors caused by various factors. Methods According to the national standard, the total radioactivity level of water samples was analyzed. Results The standard deviations of total α and total β radioactivity were less than 10% in 2014, which was 9.30% and 3.28% , respectively. And the detection results were ideal. The standard deviations of the total β radioactivity were all less than 15% in 2009, 2010, 2014 and 2016, and that of the total α radioactivity were more than 20% in 2009 and 2010. Conclusion High quality control in each process should be put to ensure the accuracy of the test results in the process of total radioactivity detection; through laboratory comparison, the problems in the measurement of the total radioactivity of laboratory water samples are found to improve the laboratory inspection ability.
